FTDI사의 FT232H칩을 탑재한 제품으로 USB를 이용하여 GPIO, SPI, I2C, UART, JTAG, 등등의 통신이 가능하게 디자인 된 제품입니다.
USB를 통해 GPIO를 일고 쓸수 있기 때문에 LED를 깜박이거나 스위치를 읽거나 등등의 작업을 수행할 수 있습니다.
여러 시리얼 프로토콜을 본 모듈을 통해 컴퓨터에서 쉽게 통신할 수 있어, 작은 OLED 디스플레이를 동작시키거나, 컬러 센서의 값을 읽는 등의 작업을 컴퓨터에서 할 수 있습니다.
파이선과 같은 스크립트를 PC에서 작성 후 특정 제품을 테스트하고자 할때도 용이합니다.

After the board +5V pin is connected to the 5V power supply or inserted into the USB female port, since the LDO function is integrated in the chip, the +3.3V pin and the Vcore pin can be connected without external connection.
